# Profile provides a way to Profile your Ruby application. # # Profiling your program is a way of determining which methods are called and # how long each method takes to complete. This way you can detect which # methods are possible bottlenecks. # # Profiling your program will slow down your execution time considerably, # so activate it only when you need it. Don't confuse benchmarking with # profiling. # # There are two ways to activate Profiling: # # == Command line # # Run your Ruby script with <code>-rprofile</code>: # # ruby -rprofile example.rb # # If you're profiling an executable in your <code>$PATH</code> you can use # <code>ruby -S</code>: # # ruby -rprofile -S some_executable # # == From code # # Just require 'profile': # # require 'profile' # # def slow_method # 5000.times do # 9999999999999999*999999999 # end # end # # def fast_method # 5000.times do # 9999999999999999+999999999 # end # end # # slow_method # fast_method # # The output in both cases is a report when the execution is over: # # ruby -rprofile example.rb # # % cumulative self self total # time seconds seconds calls ms/call ms/call name # 68.42 0.13 0.13 2 65.00 95.00 Integer#times # 15.79 0.16 0.03 5000 0.01 0.01 Fixnum#* # 15.79 0.19 0.03 5000 0.01 0.01 Fixnum#+ # 0.00 0.19 0.00 2 0.00 0.00 IO#set_encoding # 0.00 0.19 0.00 1 0.00 100.00 Object#slow_method # 0.00 0.19 0.00 2 0.00 0.00 Module#method_added # 0.00 0.19 0.00 1 0.00 90.00 Object#fast_method # 0.00 0.19 0.00 1 0.00 190.00 #toplevel module Profiler__ class Wrapper < Struct.new(:defined_class, :method_id, :hash) # :nodoc: private :defined_class=, :method_id=, :hash= def initialize(klass, mid) super(klass, mid, nil) self.hash = Struct.instance_method(:hash).bind(self).call end def to_s "#{defined_class.inspect}#".sub(/\A\#<Class:(.*)>#\z/, '\1.') << method_id.to_s end alias inspect to_s end # internal values @@start = nil # the start time that profiling began @@stacks = nil # the map of stacks keyed by thread @@maps = nil # the map of call data keyed by thread, class and id.
